useversion	'v3'	Selects the version of MS2asdm to be used

Parameter Explanations

vis

''

Name of input visibility file

Default: none

Example: vis=’ngc5921.ms’

asdm

''

Name of output ASDM directory (on disk)

Default: none

datacolumn

'data'

Which data column(s) to use for processing

(case-insensitive). Default: ‘corrected’ Options: ‘data’, ‘model’, ‘corrected’, ‘all’,’float_data’, ‘lag_data’, ‘float_data,data’, ‘lag_data,data’

Example: datacolumn=’data’

NOTE: ‘all’ = whichever of the above that are present. If the requested column does not exist, the task will exit with an error.

archiveid

'S0'

The X0 in uid://X0/X1/X2

Default: ‘S0’

rangeid

'X1'

The X1 in uid://X0/X1/X2

Default: ‘X1’

subscanduration

'24h'

Maximum duration of a subscan in the output ASDM

Default: 24h

sbduration

'2700s'

Maximum duration of a scheduling block (and therefore exec block) in the output ASDM

Default: ‘2700s’

The sbduration parameter controls the number of execution blocks (EBs) into which exportasdm subdivides the visibilities from your input MS. If the total observation time in the MS is shorter than what is given in sbduration, a single EB will be created.

apcorrected

False

Data to be marked as having atmospheric phase correction

Default: False Options: False|True

verbose

True

Produce log output?

Default: True Options: True|False

showversion

True

Report the version of ASDM class set being used

Default: True Options: True|False

useversion

'v3'

Selects the version of MS2asdm to be used

Default: ‘v3’
